2013-07-03drivers: avoid parsing names as kthread_run() format stringsKees Cook

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC specific changes from Arnd Bergmann: "These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this. Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

By enabling CONFIG_MEDIA_ATTACH, the configuration becomes valid, as dvb_attach() macro loads the module if needed, making the symbol available to the builtin module. While this bug started to appear after the patches that use IS_DEFINED macro (like changeset 7b34be71db533f3e0cf93d53cf62d036cdb5418a), this bug is a way ancient than that. The thing is that, before the IS_DEFINED() patches, the logic used to be: && defined(MODULE)) struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe, u8 i2c_addr, struct i2c_adapter *i2c); static inline struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe, u8 i2c_addr, struct i2c_adapter *i2c) { printk(KERN_WARNING "%s: driver disabled by Kconfig\n", __func__); return NULL; } The above code, with the .config file used, was evoluting to FALSE (instead of TRUE as it should be, as CONFIG_DVB_ZL10039 is 'm'), and were adding the static inline code at saa7134-dvb, instead of the external call. So, while it weren't producing any compilation error, the code weren't working either. So, as the overhead for using CONFIG_MEDIA_ATTACH is minimal, just enable it, if MODULES is defined.

2013-06-20[media] s5p makefiles: don't override other selections on obj-[ym]Mauro Carvalho Chehab

2013-06-09firewire: introduce fw_driver.probe and .remove methodsStefan Richter
FireWire upper layer drivers are converted from generic struct driver.probe() and .remove() to bus-specific struct fw_driver.probe() and .remove(). The new .probe() adds a const struct ieee1394_device_id *id argument, indicating the entry in the driver's device identifiers table which matched the fw_unit to be probed. This new argument is used by the snd-firewire-speakers driver to look up device-specific parameters and methods. There is at least one other FireWire audio driver currently in development in which this will be useful too. The new .remove() drops the unused error return code. Although all in-tree drivers are being converted to the new methods, support for the old methods is left in place in this commit. This allows public developer trees to merge this commit and then move to the new fw_driver methods.

2013-06-08[media] cx88: fix NULL pointer dereferenceHans Verkuil
This fixes a NULL pointer deference when loading the cx88_dvb module for a Hauppauge HVR4000. The bugzilla bug report is here: https://bugzilla.kernel.org/show_bug.cgi?id=56271 The cause is that the wm8775 is optional, so even though the board info says there is one, it doesn't have to be there. Checking whether the module was actually loaded is much safer. Note that this driver is quite buggy when it comes to unloading and reloading modules. Unloading cx8800 and reloading it again will still cause a crash, most likely because either the i2c bus isn't unloaded at the right time and/or the v4l2_device_unregister isn't called at the right time.

2013-06-08[media] exynos4-is: Ensure fimc-is clocks are not enabled until properly ↵Sylwester Nawrocki
configured Use clk_prepare_enable/clk_unprepare_disable instead of preparing the clocks during the driver initalization and then using just clk_disable/ clk_enable. The clock framework doesn't guarantee a clock will not get enabled during e.g. clk_set_parent if clk_prepare has been called on it. So we ensure clk_prepare() is called only when it is safe to enable the clocks, i.e. the parent clocks and the clocks' frequencies are set. It must be ensured the FIMC-IS clocks have proper frequencies before they are enabled, otherwise the whole system will hang.

2013-06-03[media] s5p-mfc: Remove special clock usage in driverArun Kumar K
MFC uses two clocks - MFC gate clock and special clock which is named as "sclk_mfc" in exynos4 and "aclk_333" in exynos5 SoC. The driver was doing just a clk_prepare on this special clock without a clk_enable call. As this sclk is the parent of gate clock, it gets prepared and enabled along with the gate clock. So there is no need for the driver to use this sclk. This patch removes the sclk usage from driver.

2013-05-23OMAPDSS: Fix crash with DT bootTomi Valkeinen
When booting with DT, there's a crash when omapfb is probed. This is caused by the fact that omapdss+DT is not yet supported, and thus omapdss is not probed at all. On the other hand, omapfb is always probed. When omapfb tries to use omapdss, there's a NULL pointer dereference crash. The same error should most likely happen with omapdrm and omap_vout also. To fix this, add an "initialized" state to omapdss. When omapdss has been probed, it's marked as initialized. omapfb, omapdrm and omap_vout check this state when they are probed to see that omapdss is actually there.
